Propranolol for the treatment of cyclosporine-induced headaches.

We studied whether small doses of propranolol given orally have an effect on headaches that are associated with intravenous cyclosporine therapy. In seven patients who had severe cephalalgia associated with intravenous cyclosporine post-bone marrow transplant, oral propranolol promptly relieved the symptoms in four patients. Intravenous propranolol was not effective in one patient who was unable to take oral medications. Propranolol should be considered as an alternative to chronic narcotics in patients with headaches due to cyclosporine.
